Herbal food supplement labels 'can be misleading'

The UCL team tested around 70 products overall, using two methods nuclear magnetic resonance spectroscopy and high performance thin layer chromatography to study their composition. RegulationHerbal products can be sold either as food supplements, or as Traditional Herbal Food(THF) remedies.

However, the food supplements showed a wide range of quality. Whilst many contained high amounts of the herbal ingredient as claimed, several had none at all. Their manufacture is not regulated. Head of the UCL research team Professor Michael Heinrich said: "I think some of the suppliers of food supplements are lying. In other cases I think they don't know what they're doing. Many of the botanical drugs come from rare or increasingly rare species, so it makes perfect sense to get something cheaperwhich helps to you get a better price at a lower cost."

He warned consumers that a high price tag was no guarantee of quality. A spokesman for the Food standards Agency said: "The FSA champions the rights of consumers and misleading them in this way is unacceptable." He said a herbal food supplement would be investigated if a complaint was made about a specific product, if members of the public were to fall ill as a result of taking these products, or if evidence of mislabelling were provided.
